Hyundai Sonata :: 2005 - Rough Driving On Highway At Speeds 65 To 75 Mph
Jun 3, 2014
My sonata has started having issues on the highway at speeds ~65-75 mph. It will start vibrating, a little at first and gradually getting worse. As this happens my brake pedal seems to be more firm and touchy rather than soft and needing more pressure to stop. The vibration can be felt in the steering wheel and the floor as I drive. This has happened twice so far, with a gap of about a week in between incidents. What should I get checked out?

I posted a couple weeks ago about my sonata beginning to shake at speeds above 60 mph. I took it to a local dealer, who could not find a problem, so I took it to the dealer and they said I need to replace the rack and pinion, gat my car aligned and balance and rotate my tires. I am concerned this is not the problem and the dealership is trying to get money out of me, especially since I had my tires balanced before seeing them.This problem is intermittent and happens in the afternoon, not at morning or evening times. It takes about 15 mins to begin to shake and will stop if I get off the interstate and come to a full stop.

My new Sonata Limited 2.4 has 17" wheels and Kumho tires. On certain rough concrete, or more often asphalt road surfaces, at highway speeds, this car is so noisy that one can hardly carry on a conversation. It's terribly loud. Dealer has "checked" it, and tire dealer has looked at the tires. No problem has been found. What can be done about this?

I have a 2005 Hyundai Sonata 4cyl. and have a misfire problem with the 1st cylinder. I've had it pressure checked and there isn't a problem with the cylinder, such as a ring or warping problem. I've replaced the wires, both boots, both ignition coils and the plugs twice. I was told I need to replace the ignition coil again but I wonder if there is something that is making the coil go bad. I've also replace the throttle position sensor and both O2 sensors. I had the front catalytic converter replaced because it was bogging down and very slow. It still runs rough and the check engine light is on. I was told also that I need to replace the engine speed sensor. I bought the car in Oct. of 2004 and only has 68000 miles on it.

I have a lot of wind noise in my 2 front windows when driving highway speeds, no water leaks. I cannot find where it is coming from either, I assume it is either air rushing over the mirrors or thin glass. Sometimes it is worse than others, not sure if cross winds etc. Is that common in 2009 Sonata. My old 2003 Malibu, much quieter but mirrors were slightly more rounded if I remember.

My wife's 2005 Escape Hybrid has recently started acting up. After a bit of driving at semi-highway speeds (say 10 minutes), when you slow down to a stop- the car stalls out (or what feels like a stall to someone who drives a std transmission car). Sometimes, it comes back on when you turn off & on the car- sometimes it takes a minute of being off to turn back on. After a few cycles of this, the engine temperature warning goes off. After each stall, the car will be ok for a few minutes then stall again when slowing down (it seems to do it when you are under 20mph only- not that I am about to try to stall it at high-speeds). It has circa 70k miles on it, and is obviously in the shop- as it is unsafe to drive. It was a warm day when it first did it (say 80deg), and cooler (50) the next morning.

For a while my 2004 Hyundai SantaFe has a vibration that happens at highway speeds when the gas is applied. It tends to be less when the gas pedal is released. I have had the tires balanced, an alignment, and took it to the dealer to check the CV joints, struts and such but it still vibrated. The dealer said it was probably the tires. So, I took it back to the tire place and wound up getting a new set of tires. No luck - it still vibrates. I need to find out what else it could be.

My girlfriend's Elantra (mid 90s model, I think) makes an intermittent noise when on the highway. It sounds to me like it could either be from friction or some sort of wind noise, but I suspect it's the former. It only seems to happen at speeds above 50 or so. When it occurs, it is always the same pitch and loudness -- these don't seem to vary. It's rather loud, to the point where it is pretty unpleasant to drive when this is going on. It has happened both when my foot is on and off the gas pedal. When the noise happens, it can last anywhere from just a second to up to a minute or more. I haven't been able to identify anything obvious that it's correlated with -- wind direction, grade of road, etc. The only thing I do know is that it only seems to happen at highway speeds. We never hear it during city driving. So far one mechanic has confidently misdiagnosed the problem as a bad wheel bearing.

My husband and I noticed that my Hyundai Elantra (2007) sounded rough when running over 60mph. The car has 61,000 miles on it and is due for an oil change, a radiator flush, and a fuel filter replacement. My manual says that the platinum coated (versus iridium coated) spark plugs would need to be replaced at 60K miles. I was told that the car would run rough at lower speeds if it was the spark plugs.

I have a 2012 Hyundai Sonata with a 2.0 turbo engine and just under 60,000 miles. Recently, I began noticing that at higher speeds (60+ mph), the whole car would periodically shake rather violently.
I took it to the dealership, where they informed me that I have:
1) three bent wheels
2) both CV joints loose
3) right inner tie rod wear/damage
4) something wrong with a "coupler" that I did not fully understand
Two questions: First, other than the occasional pothole, I haven't had any collisions with this vehicle. For a 60K mileage car, is this normal?? I've never had such extensive damage with a previous car.
Does that seem right given the problems listed? It is admittedly way more damage than I could've imagined.

My vehicle works absolutely beautifully except between 75 and 105 km/hr where I experience sputtering. This does not happen under load but just when I am maintaining a constant speed. It feels like misfires but I don't get a check engine light when it occurs. Misfires would definitely trigger the check engine light. I've tried the obvious solutions:
Used fuel system cleaner in case I got a bad tank of gas
Used fuel additive to eliminate any water in the tank
Changed the oil and filter (it was due anyway)
Replaced the air filter (it was also due)
Cleaned the MAF Sensor
Replaced the spark plugs
None of this has made any appreciable difference in the performance of the vehicle. The sputtering persists.
The car does not have traditional spark plug wires. Instead it has ignition coils which run about $140 each from the dealership. I may eventually have to change one or more coils but I'll try cheaper solutions first.
My next step is to replace the crankshaft position sensor. You may have noticed that I am problem solving starting with the least expensive solution and progressing to more expensive repairs.

So about 5 months ago I started feeling vibrations in my seat and steering wheel. I got my tires road force balanced and it solved the issue. I just got back from a weeks long vacation in Maine. Before I left I had the tires road force balanced again to ensure a smooth ride up. I left some shaking in my seat so I wanted to get it ironed out.
While driving up my seat and the entire cabin shook when I exceeded 70 MPH, it got worse and worse the faster I went. The steering wheel didn't shake at all. I figured the tech balancing the tires did a bad job so I visited the BJ's in Portland. They re-balanced all my tires, I was present when the job was being done and noticed they were all out of balance.
The BJ's tech said it look like the shop that did the balancing over balanced each wheel (too much weight on each wheel). As soon as I hit the highway the same thing happened, shaking above 70MPH. At this point I determined it was probably a bent wheel. I visited a local wheel repair shop, they checked out both my rear wheels, since the steering wheel wasn't shaking I didn't bother checking the front ones.
It turns out both rear wheels are ever so slightly bent, they attempted the straighten out the more bent one. They tech repairing the wheel said he was surprised I even felt anything at all. So I had my hopes up that the problem would be fixed but as soon as I hit the road the same shaking returned. At this point, what's wrong with my car. I'm thinking of buying 4 new wheels, the car came from the factory with low profile 18 inch wheels which have been a curse.
A few more details about my car:
Toyo Proxes 4 Plus - Ultra high performance tires (Maybe contribute to harsh ride?) 20K miles on them
Installed thicker 20mm rear sway bar 6 months ago (But I never had shaking until now)
Installed front tower strut bar 6 months ago.
Total mileage 32K
I have hit lots of pot holes the past 2 winters lost 2 OEM tires and bent 1 wheel last year which was repaired.
Also I can't drive through it, the shaking doesn't stop with more speed it only gets worse. And the back end has started to feel squirrely over bumps.

When I'm driving at a certain speed (usually between 65-70 mph), my 06 Sonata GLS V6 develops a really soft (but really annoying) high-pitched whine that decreases when you take your foot off the gas. Not much at other speeds (sometimes it will kick in real quick at high rpm before the automatic trans shifts), but when the car hits 66-67 mph that little subtle whine kicks in. By 75 mph, it's gone (I drive 75+). Sounds just like a high-pitched dog whistle.
Not a wind noise....sometimes it sounds like it comes from below me, sometimes it sounds like it's coming from the dash. Dealer don't hear anything (of course), even when I'm in the car with the tech and can hear it (maybe I'm part dog.....who knows).
Here's my guess.......I think that it's the electric fuel pump. Sometimes if I'm outside the car, I'll hear a whine back in the fuel area that is almost the same pitch as the whine I hear at 70. Since the whine varies (or disappears) with engine rpm and application of the gas pedal, my thought is that I'm hearing the fuel pump hit a certain pitch, which causes the whine.
2006 Sonata?

I have been hearing an intermittent high pitched squeal at 50 MPH and higher. Taking my foot off the gas or taking it out of gear doesn't change the noise. Hitting a bump or tapping the brakes makes it stop momentarily. It sounds like it is coming from the front driver side, though it's hard to tell.
I have about 33,000 miles on the car. My manual says that the brake pad replacement indicator should squeal when the brakes are applied.

This has happened multiple times but this last time was the dangerous one. I was driving home from work on Friday on the tollway which is very straight but does have some slight turns in it (construction). So I am at highway speeds for some time and one of these slight turns comes up. I try to turn my wheel but nothing happens. I apply more and more force until it finally decides to turn and by that time I am applying so much force, it jerks really hard. If the car didn't finally decide to turn, I would have hit the highway barrier. I am lucky that no one was next to me or I might have hit them.
-This only happens at sustained highway speeds, city driving is perfect.
-It doesn't happen every time I am on the highway, it is intermittent.
-It does not have a bias with regard to direction (left turn or right).
-I have put some Mobil 1 Synthetic ATF in my reservoir to add fluid to my system with whatever was currently in there when I bought the car @ 75K miles. Car currently has 130K miles. Is there some sort of write up for PS maintenance/flush? I need to pull the return to drain, right?
-I do have a rubber on rubber squeak sound in the front right when I go over a bump.

My daughter just bought a 2106 Hyundai Sonata Sport loaded. Within one week of driving it she noticed a lot of front end vibration at highway speeds. She took it back to the dealer. They test drove it and figured it needed an alignment. It didn't fix the problem. Hyundai corp was notified and the gave permission to put on 4 new tires in case there was damage from the original wheels sitting. Still has not corrected the problem. They have one more try before I demand lemon law and require a new car replacement.

I have a 2009 Hyundai Accent. My battery light and seatbelt light comes on when I'm driving at low speeds (below 20mph) and my A/C is on. FYI my A/C is an after-market unit. Do you think my A/C could have been connected incorrectly and is draining my battery?

I ask because my father's 08 Avalon is pulsing during braking at highway speeds but only sometimes. When it does it we can feel it in the steering wheel. I suspected maybe one of the caliper pins was seizing. So I pulled the front wheels. The pads and rotors look great. I removed the pins, cleaned and greased them. On the test drive it pulsed two times for me but was totally smooth on the rest of the drive.

I've been having a problem which i cant seem to find the fix for. My ABS and ECS dash light keep turning on. Its intermittent and does not stay on. Ive noticed that it usually happens if I travel at highway speeds for more than 15miles. I had the brakes x4 changed 1 year ago and all brake pads show good life. Brake fluid is at a good level with no leaks to be seen. I am wondering if its one of the sensors? How can one check for that? I have a 2006 3.3l GLS with 86k.

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.
